One of the big challenges around activating people on the issue of climate change is that there are a myriad of campaigns, big ones, small local ones, all over the world. I really wanted to address this issue, to provide a single platform that all campaigns and websites can use to collectively show the vote. So I developed a "web element" similar in function to Google's Web Elements, which anyone can insert to allow people to vote, show the vote and provide educational tools on their own website by simply filling out the publisher form, and copying and pasting a single line of HTML code.

Show Your Vote has three tabs: Vote, Explore, and Learn. The Vote tab allows individuals and organisations to show their vote.

The Explore tab displays individual votes aggregated by post code, and organisations by their own custom icons. The voting map is powered by Google Maps API. Additionally, social networking tools powered by Google Friend Connect allow people within the global community to share their messages of support. Individual votes are aggregated into post codes, and organisations can upload their own icon to the map.

Finally, the Learn tab contains rich educational pieces, narrated by some of the top names in science, NGOs and the political world. These tours were created by the Google Earth Outreach team using Google Earth's new touring capabilities.

In the countdown to the Copenhagen Climate Conference, I'm hopeful that we can collect enough of the world's public show of support to help amplify the need to change climate change, to drive collective action and to reinforce the need for our world leaders to act now. Please join me in helping to show the vote!

I'd like to thank fellow Googlers Pamela Fox, Bob Aman, Rupert Breheny and Benjamin Kott for volunteering their time in helping to make Show Your Vote possible.
